Cross Reference to Related Applications

This patent application claims priority from U.S. provisional patent application No.63/200,974 entitled "CYCLIC SHIFT MAPPINGFOR MULTIPLEXED MESSAGES WITH DIFFERENT priority for cyclic shift mapping of multiplexed messages having different PRIORITIES" filed on month 4 and 6 of 2021 and U.S. non-provisional patent application No.17/457,540 entitled "CYCLIC SHIFT MAPPINGFOR MULTIPLEXED MESSAGES WITH DIFFERENT priority for cyclic shift mapping of multiplexed messages having different PRIORITIES" filed on month 12 and 3 of 2021, which are hereby expressly incorporated herein by reference.

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to techniques and apparatus for cyclic shift mapping of multiplexed messages with different priorities for wireless communications.

Background

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple-access techniques capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access techniques include Code Division Multiple Access (CDMA) systems, time Division Multiple Access (TDMA) systems, frequency Division Multiple Access (FDMA) systems, orthogonal Frequency Division Multiple Access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-advanced is an enhancement set to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the third generation partnership project (3 GPP).

A wireless network may include one or more base stations supporting communication for one or more User Equipment (UEs). The UE may communicate with the base station via downlink and uplink communications. "downlink" (or "DL") refers to the communication link from a base station to a UE, and "uplink" (or "UL") refers to the communication link from a UE to a base station.

The above multiple access techniques have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region, and/or global level. The New Radio (NR), which may be referred to as 5G, is an enhanced set of LTE mobile standards promulgated by 3 GPP. NR is designed to better support mobile broadband internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with cyclic prefix (CP-OFDM) on the downlink, CP-OFDM and/or single carrier frequency division multiplexing (SC-FDM) on the uplink (also known as discrete fourier transform spread OFDM (DFT-s-OFDM) and supporting beamforming, multiple Input Multiple Output (MIMO) antenna techniques and carrier aggregation to improve spectral efficiency, reduce cost, improve services, utilize new spectrum, and integrate better with other open standards.

Various aspects of the disclosure are described more fully below with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed, whether implemented independently or combined with any other aspect of the disclosure.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

Several aspects of a telecommunications system will now be presented with reference to various apparatus and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

Although aspects may be described herein using terms commonly associated with 5G or New Radio (NR) Radio Access Technologies (RATs), aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and/or RATs after 5G (e.g., 6G).

Fig. 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and/or a 4G (e.g., long Term Evolution (LTE)) network, etc., or may include elements thereof. Wireless network 100 may include one or more base stations 110 (shown as BS110a, BS110b, BS110c, and BS110 d), one or more User Equipments (UEs) 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120 e), and/or other network entities. Base station 110 is the entity in communication with UE 120. Base stations 110 (sometimes referred to as BSs) may include, for example, NR base stations, LTE base stations, node BS, enbs (e.g., in 4G), gnbs (e.g., in 5G), access points, and/or Transmission and Reception Points (TRPs). Each base station 110 may provide communication coverage for a particular geographic area. In the third generation partnership project (3 GPP), the term "cell" can refer to a coverage area of a base station 110 and/or a base station subsystem serving the coverage area, depending on the context in which the term is used.

Base station 110 may provide communication coverage for a macrocell, a picocell, a femtocell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs 120 associated with the femto cell (e.g., UEs 120 in a Closed Subscriber Group (CSG)). The base station 110 for a macro cell may be referred to as a macro base station. The base station 110 for a pico cell may be referred to as a pico base station. The base station 110 for a femto cell may be referred to as a femto base station or a home base station. In the example shown in fig. 1, BS110a may be a macro base station for macro cell 102a, BS110b may be a pico base station for pico cell 102b, and BS110c may be a femto base station for femto cell 102 c. A base station may support one or more (e.g., three) cells.

In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile base station 110 (e.g., a mobile base station). In some examples, base stations 110 may be interconnected with each other and/or to one or more other base stations 110 or network nodes (not shown) in wireless network 100 through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., base station 110 or UE 120) and send the transmission of the data to a downstream station (e.g., UE120 or base station 110). The relay station may be a UE120 capable of relaying transmissions for other UEs 120. In the example shown in fig. 1, BS110d (e.g., a relay base station) may communicate with BS110a (e.g., a macro base station) and UE120 d to facilitate communications between BS110a and UE120 d. The base station 110 relaying communications may be referred to as a relay station, a relay base station, a relay, and so on.

The wireless network 100 may be a heterogeneous network including different types of base stations 110 (such as macro base stations, pico base stations, femto base stations, or relay base stations, etc.). These different types of base stations 110 may have different transmit power levels, different coverage areas, and/or different effects on interference in the wireless network 100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations may have a lower transmit power level (e.g., 0.1 to 2 watts).

The network controller 130 may be coupled or in communication with a set of base stations 110 and may provide coordination and control of these base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. Base stations 110 may communicate with each other directly or indirectly via wireless or wired backhaul communication links.

The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a mobile station, and/or a subscriber unit. UE 120 may be a cellular telephone (e.g., a smart phone), a Personal Digital Assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a Wireless Local Loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, a super-book, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smartwristband, smart jewelry (e.g., a smartring or smartband)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), an in-vehicle component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless medium.

Some UEs 120 may be considered Machine Type Communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and/or eMTC UEs may include, for example, robots, drones, remote devices, sensors, gauges, monitors, and/or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered internet of things (IoT) devices and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered client devices. UE 120 may be included within a housing that houses components of UE 120, such as processor components and/or memory components. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. The RAT may be referred to as a radio technology, an air interface, etc. The frequencies may be referred to as carriers, frequency channels, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120 e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, a vehicle-to-vehicle (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by base station 110.

Devices of the wireless network 100 may communicate using electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., by frequency or wavelength. For example, devices of wireless network 100 may communicate using one or more operating frequency bands. In 5G NR, two initial operating bands have been identified as frequency range designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be appreciated that although a portion of FR1 is greater than 6GHz, FR1 is commonly (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. Similar naming problems sometimes occur with respect to FR2, which is commonly (interchangeably) referred to as the "millimeter wave" band in various documents and articles, although it is different from the Extremely High Frequency (EHF) band (30 GHz-300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" band.

The frequency between FR1 and FR2 is commonly referred to as the mid-band frequency. Recent 5G NR studies have identified the operating band of these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). The frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics and thus may effectively extend the characteristics of FR1 and/or FR2 into mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been identified as frequency range designation FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz) and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF frequency band.

In view of the above examples, unless specifically stated otherwise, it should be understood that, if used herein, the term "sub-6 GHz" and the like may broadly represent frequencies that may be less than 6GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless specifically stated otherwise, it should be understood that the term "millimeter wave" or the like, if used herein, may broadly mean frequencies that may include mid-band frequencies, may be within FR2, FR4-a, or FR4-1 and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4-a, FR4-1, and/or FR 5) may be modified, and that the techniques described herein are applicable to those modified frequency ranges.

In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 can generate a multiplexed message including first information having a first priority and second information having a second priority, wherein the first priority is higher than the second priority; and transmitting the multiplexed message using a particular cyclic shift of a particular cyclic shift set of the plurality of cyclic shift sets, wherein the particular cyclic shift set is based at least in part on the first information and the particular cyclic shift is based at least in part on the second information. Additionally or alternatively, communication manager 140 may perform one or more other operations described herein.

In some aspects, the base station 110 may include a communication manager 150. As described in more detail elsewhere herein, communication manager 150 may receive a multiplexed message using a particular cyclic shift of a particular set of cyclic shifts of a plurality of sets of cyclic shifts, wherein the particular set of cyclic shifts is based at least in part on first information of the multiplexed message and the particular cyclic shift is based at least in part on second information of the multiplexed message, wherein the first information is associated with a first priority and the second information is associated with a second priority that is lower than the first priority; and decoding the multiplexed message to determine a first content of first information based at least in part on the particular set of cyclic shifts and to determine a second content of second information based at least in part on the particular cyclic shift. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

As indicated above, fig. 1 is provided as an example. Other examples may differ from the example described with respect to fig. 1.

Fig. 2 is a diagram illustrating an example 200 in which a base station 110 is in communication with a UE 120 in a wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a through 234T, such as T antennas (T.gtoreq.1). UE 120 may be equipped with a set of antennas 252a through 252R, such as R antennas (r≡1).

At base station 110, transmit processor 220 may receive data intended for UE 120 (or a group of UEs 120) from data source 212. Transmit processor 220 may select one or more Modulation and Coding Schemes (MCSs) for UE 120 based at least in part on one or more Channel Quality Indicators (CQIs) received from UE 120. Base station 110 may process (e.g., encode and modulate) data for UE 120 based at least in part on the MCS(s) selected for UE 120 and may provide data symbols to UE 120. Transmit processor 220 may process system information (e.g., for semi-Static Resource Partitioning Information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary Synchronization Signals (PSS) or Secondary Synchronization Signals (SSS)). A Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and/or reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modulators) (shown as modems 232a through 232T). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 may process a respective output symbol stream (e.g., for OFDM) using a respective modulator component to obtain an output sample stream. Each modem 232 may further process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. Modems 232a through 232T may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a through 234T).

At UE 120, a set of antennas 252 (shown as antennas 252a through 252R) may receive the downlink signals from base station 110 and/or other base stations 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254R). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 may condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal using a corresponding demodulator component to obtain input samples. Each modem 254 may use a demodulator assembly to further process the input samples (e.g., for OFDM) to obtain received symbols. MIMO detector 256 may obtain the received symbols from modem 254, may perform MIMO detection on the received symbols, if applicable, and may provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for UE 120 to data sink 260, and may provide decoded control information and system information to controller/processor 280. The term "controller/processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, and/or a CQI parameter, among others. In some examples, one or more components of UE 120 may be included in housing 284.

The network controller 130 may include a communication unit 294, a controller/processor 290, and a memory 292. The network controller 130 may comprise, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via a communication unit 294.

The one or more antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252 r) may include or be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, etc. The antenna panel, antenna group, antenna element set, and/or antenna array may include one or more antenna elements (within a single housing or multiple housings), a coplanar antenna element set, a non-coplanar antenna element set, and/or one or more antenna elements coupled to one or more transmission and/or reception components (such as one or more components of fig. 2).

On the uplink, at UE 120, transmit processor 264 may receive and process data from data source 262 and control information from controller/processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and/or CQI). Transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, modem 254 of UE 120 may include a modulator and a demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modem(s) 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., with reference to fig. 4A-8).

At base station 110, uplink signals from UE 120 and/or other UEs may be received by antennas 234, processed by modems 232 (e.g., the demodulator components of modems 232, shown as DEMODs), detected by MIMO detector 236 if applicable, and further processed by receive processor 238 to obtain decoded data and control information sent by UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller/processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. Base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and/or uplink communications. In some examples, modem 232 of base station 110 may include a modulator and a demodulator. In some examples, base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modem(s) 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., with reference to fig. 4A-8).

The controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of fig. 2 may perform one or more techniques associated with cyclic shift mapping for multiplexed messages including different priority information, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of fig. 2 may perform or direct operations such as process 500 of fig. 5, process 600 of fig. 6, and/or other processes as described herein. Memory 242 and memory 282 may store data and program codes for base station 110 and UE 120, respectively. In some examples, memory 242 and/or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and/or UE 120 (e.g., directly, or after compilation, conversion, and/or interpretation), may cause the one or more processors, UE 120, and/or base station 110 to perform or direct operations such as process 500 of fig. 5, process 600 of fig. 6, and/or other processes described herein. In some examples, executing instructions may include executing instructions, converting instructions, compiling instructions, and/or interpreting instructions, among others.

In some aspects, UE 120 includes means for generating a multiplexed message comprising first information having a first priority and second information having a second priority, wherein the first priority is higher than the second priority; and/or transmitting the multiplexed message using a particular cyclic shift of a particular set of cyclic shifts of the plurality of sets of cyclic shifts, wherein the particular set of cyclic shifts is based at least in part on the first information and the particular cyclic shift is based at least in part on the second information. Means for UE 120 to perform the operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282.

In some aspects, the base station 110 includes means for receiving a multiplexed message using a particular cyclic shift of a particular cyclic shift set of a plurality of cyclic shift sets, wherein the particular cyclic shift set is based at least in part on first information of the multiplexed message and the particular cyclic shift is based at least in part on second information of the multiplexed message, wherein the first information is associated with a first priority and the second information is associated with a second priority that is lower than the first priority; and/or means for decoding the multiplexed message to determine a first content of first information based at least in part on the particular set of cyclic shifts and to determine a second content of second information based at least in part on the particular cyclic shift. Means for base station 110 to perform the operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller/processor 240, memory 242, or scheduler 246.

Although the blocks in fig. 2 are illustrated as distinct components, the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combination of components or a combination of various components. For example, the functions described with respect to transmit processor 264, receive processor 258, and/or TX MIMO processor 266 may be performed by controller/processor 280 or under the control of controller/processor 280.

As indicated above, fig. 2 is provided as an example. Other examples may differ from the example described with respect to fig. 2.

Fig. 3 is a diagram illustrating an example 300 of physical channels and reference signals in a wireless network according to the present disclosure. As shown in fig. 3, the downlink channel and the downlink reference signal may carry information from the base station 110 to the UE 120, and the uplink channel and the uplink reference signal may carry information from the UE 120 to the base station 110.

As shown, the downlink channel may include examples of a Physical Downlink Control Channel (PDCCH) carrying Downlink Control Information (DCI), a Physical Downlink Shared Channel (PDSCH) carrying downlink data, or a Physical Broadcast Channel (PBCH) carrying system information, etc. PDSCH communications may be scheduled by PDCCH communications. As further shown, the uplink channel may include a Physical Uplink Control Channel (PUCCH) carrying Uplink Control Information (UCI), a Physical Uplink Shared Channel (PUSCH) carrying uplink data, or a Physical Random Access Channel (PRACH) for initial network access, or the like. UE 120 may transmit Acknowledgement (ACK) or Negative Acknowledgement (NACK) feedback (e.g., ACK/NACK feedback or ACK/NACK information) in UCI on PUCCH and/or PUSCH.

The PUCCH may convey different types of payload data, such as a Scheduling Request (SR) or a hybrid automatic repeat request (HARQ) feedback message, and so forth. For example, the PUCCH may include a 1-bit SR in PUCCH format 0 that overlaps (e.g., in terms of time resources) with a 1-or 2-bit HARQ ACK message in PUCCH format 0. Different messages included in the PUCCH may be associated with different priorities. For example, a 1-bit SR may have a relatively high priority, and a 1-or 2-bit HARQ-ACK may have a relatively low priority. Similarly, a 1 or 2 bit HARQ-ACK may have a relatively high priority, and a 1 bit SR may have a relatively low priority. Other types of payloads may have other types or levels of priority. In addition, combinations of payloads may be possible. For example, the PUCCH may convey a first payload comprising a first bit of a message having a first priority on a first frequency and may convey a second payload comprising a second bit of a message having a second priority on a second frequency.

As further illustrated, the downlink reference signals may include Synchronization Signal Blocks (SSBs), channel State Information (CSI) reference signals (CSI-RS), DMRS, positioning Reference Signals (PRS), or Phase Tracking Reference Signals (PTRS), or the like. As also shown, the uplink reference signals may include Sounding Reference Signals (SRS), DMRS, PTRS, or the like.

SSBs may carry information for initial network acquisition and synchronization, such as PSS, SSS, PBCH and PBCH DMRS. SSBs are sometimes referred to as sync signal/PBCH (SS/PBCH) blocks. Base station 110 may transmit multiple SSBs on multiple corresponding beams and these SSBs may be used for beam selection.

The CSI-RS may carry information for downlink channel estimation (e.g., downlink CSI acquisition), which may be used for scheduling, link adaptation, or beam management, etc. Base station 110 may configure a set of CSI-RS for UE 120 and UE 120 may measure the configured set of CSI-RS. Based at least in part on these measurements, UE 120 may perform channel estimation and may report channel estimation parameters (e.g., in CSI reports) such as CQI, precoding Matrix Indicator (PMI), CSI-RS resource indicator (CRI), layer Indicator (LI), rank Indicator (RI), or RSRP, among others, to base station 110. Base station 110 may use CSI reports to select transmission parameters for downlink communications to UE 120, such as a number of transmission layers (e.g., rank), a precoding matrix (e.g., precoder), an MCS, or refined downlink beams (e.g., using a beam refinement procedure or beam management procedure), and so forth.

The DMRS may carry information for estimating a radio channel for use in demodulating an associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH or PUSCH). The design and mapping of DMRS may be specific to the physical channel that the DMRS uses for estimation. DMRS is UE-specific, may be beamformed, may be limited to scheduled resources (e.g., rather than transmitted on wideband), and may be transmitted only when necessary. As shown, DMRS is used for both downlink and uplink communications.

PTRS may carry information for compensating for oscillator phase noise. In general, phase noise increases with increasing oscillator carrier frequency. Thus, PTRS may be utilized at high carrier frequencies (such as millimeter wave frequencies) to mitigate phase noise. PTRS can be used to track the phase of the local oscillator and enable suppression of phase noise and Common Phase Error (CPE). As shown, PTRS is used for both downlink communications (e.g., on PDSCH) and uplink communications (e.g., on PUSCH).

PRS may carry information that is used to implement timing measurements or range measurements for UE120 based on signals transmitted by base station 110 to improve observed time difference of arrival (OTDOA) positioning performance. For example, PRS may be a pseudo-random Quadrature Phase Shift Keying (QPSK) sequence mapped in a diagonal pattern with frequency and time offsets to avoid collisions with cell-specific reference signals and control channels (e.g., PDCCH). In general, PRSs may be designed to improve the detectability of UE120, and UE120 may need to detect downlink signals from multiple neighboring base stations in order to perform OTDOA-based positioning. Accordingly, UE120 may receive PRSs from a plurality of cells (e.g., a reference cell and one or more neighbor cells) and may report a Reference Signal Time Difference (RSTD) based on OTDOA measurements associated with PRSs received from the plurality of cells. Base station 110 may then calculate the location of UE120 based on the RSTD measurements reported by UE 120.

The SRS may carry information for uplink channel estimation, which may be used for scheduling, link adaptation, precoder selection, or beam management, etc. Base station 110 may configure one or more SRS resource sets for UE 120 and UE 120 may transmit SRS on the configured SRS resource sets. The SRS resource set may have configured uses such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operation, uplink beam management, and so forth. Base station 110 may measure SRS, may perform channel estimation based at least in part on these measurements, and may use SRS measurements to configure communications with UE 120.

As indicated above, fig. 3 is provided as an example. Other examples may differ from the example described with respect to fig. 3.

The UE may transmit the PUCCH using a specific base sequence at a specific Resource Block (RB) using a specific Cyclic Shift (CS) number. For example, the UE may transmit a 1-bit SR on PUCCH format 0 using the base sequence S in 1 RB and with a specific CS in the time domain. In this case, the particular CS may be a CS value between 0 and 11 (e.g., 12 discrete CS values may be permitted). In the set of possible CSs, the BS may transmit a Radio Resource Control (RRC) message to the UE to indicate which CS index i the UE is to communicate for each possible value for the message the UE is to communicate on the PUCCH. For example, the BS may configure the UE to transmit a positive SR using a CS value of 2 and not transmit to convey a negative SR.

When there are multiple possible values that the UE is to communicate via use of CS values, the BS may select CS values that are equidistant from a set of possible CS values. For example, the BS may configure the UE to transmit a 1-bit HARQ feedback message by: CS value 0 (e.g., of possible CS values 0 through 11) is used to indicate a first value of the HARQ feedback message (e.g., ACK/NACK value (a/N value) value "{0 }") and CS value 6 is used to indicate a second value of the HARQ feedback message (e.g., a/N value "{1 }). For 2-bit HARQ feedback, the BS may configure the UE to use CS value 0 (e.g., of possible CS values 0 to 11) for the first a/N value "{0,0}, CS value 3 for the second a/N value" {0,1}, CS value 6 for the third a/N value "{1,0}, and CS value 9 for the fourth a/N value" {1,0 }). Other types of payloads, values of payloads, or configurations of CS values are possible. By selecting CS values that are equidistant from the set of possible CS values, the BS maximizes the gap or interval between different selected CS values, which increases the likelihood that the BS can successfully decode the PUCCH from the UE.

When the UE is to communicate multiple payloads of the same priority, the BS may configure the UE with multiple sets of CS values to communicate the multiple payloads. For example, when the UE is to communicate both SR and HARQ feedback messages, the UE may be configured to use a first set of CS values (e.g., 0 and 6) to indicate a negative SR, and may select a first CS value (e.g., 0) of the first set of CS values to indicate an a/N value "{0}", and may select a second CS value (e.g., 6) of the first set of CS values to indicate an a/N value "{1 }). Instead, the UE may use a second set of CS values (e.g., 3 and 9) to indicate a positive SR, and may select a first CS value (e.g., 3) of the first set of CS values to indicate an a/N value "{0}", and may select a second CS value (e.g., 9) of the first set of CS values to indicate an a/N value "{1 }). In another example, for 2-bit HARQ feedback, the UE may have a first set of CS values (e.g., 0, 3, 6, 9) to indicate a negative SR and select one of the first set of CS values to indicate which a/N value is also being indicated, and a second set of CS values (e.g., 1, 4, 7, 10) to indicate a positive SR and select one of the second set of CS values to indicate which a/N value is also being indicated. In this case, the CS values within each CS value set are equidistant (e.g., 0, 3, 6, and 9 are equidistant with respect to CS values 0 through 11, as are 1, 4, 7, and 10), but as a result, the spacing between each complete CS value set is relatively small (e.g., 0 and 1 are contiguous, 3 and 4 are contiguous, etc.). The relatively small interval between sets of CS values may be referred to herein as a "neighbor set" or a "near neighbor set". Similarly, a relatively large interval between CS values within a particular set of CS values may be referred to as an "equidistant" interval, as described above, or an "opposite" interval.

When the UE has multiple payloads of different priorities, the UE may be configured to discard lower priority payloads and transmit only higher priority payloads. For example, when the UE is to transmit a high priority 1-bit SR and a low priority 1 or 2-bit HARQ feedback message, the UE may discard the low priority 1 or 2-bit HARQ feedback message and transmit the 1-bit SR. In this case, the UE may use a CS value configured to convey only 1-bit SRs (e.g., CS value 2 for positive SRs, no transmission for negative SRs, as described above). Similarly, when the UE is to transmit a high priority 1 or 2 bit HARQ feedback message and a low priority 1 bit SR, the UE may discard the 1 bit SR and transmit the 1 or 2 bit HARQ feedback message (e.g., CS value 0 or 6 for a 1 bit a/N value, or CS value 0, 3, 6, or 9 for a 2 bit a/N value, as described above).

However, discarding lower priority payloads may result in information not being conveyed to the BS. Alternatively, the UE may communicate the discarded low priority payload at another time using additional network resources for another transmission, which may result in inefficient network utilization. Some aspects described herein enable transmission of multiple payloads in a multiplexed message of a PUCCH using different cyclic shifts. Instead of selecting from adjacent or near adjacent sets with equidistant spacing, the UE may be configured to select from the opposite set with adjacent spacing. In other words, the BS may configure the UE to select a set of CS values to communicate a high priority payload and select from the selected set of CS values to communicate a low priority payload. As a specific example, in the case of a high priority 1-bit SR and a low priority 1-bit HARQ feedback message, the UE may be configured to select a first set of CS values (0, 1 of CS values 0 to 11) to convey a negative SR and a second set of CS values (6, 7 of CS values 0 to 11) to convey a positive SR.

In this case, by using a set of CS values with the largest spacing from each other (e.g., (0, 1) and (6, 7) as far as possible with respect to CS values 0 to 11, where there is a wrap around and 11 is adjacent to 0), the UE increases the likelihood that the BS can successfully decode the high priority SR bits relative to having values closer together for the SR bits as described above with respect to the two payload case with equal priority. Further to the particular example, the UE may be configured to select a particular CS value to convey low priority bits, such as selecting CS value 0 for the a/N value {0} and CS value 1 for the a/N value {1} within the CS value sets 0,1 for the negative SR. In this way, while the spacing between CS values is minimized (to maximize the spacing between sets of CS values), which may increase the likelihood that the BS will not successfully decode HARQ feedback (e.g., the BS cannot successfully distinguish between CS values 0 and CS values 1), the UE avoids discarding low priority payloads, thereby reducing the likelihood of discarded information or excessive network resource usage (as described above with respect to the case of two payloads having different priorities).

Fig. 4A-4G are diagrams illustrating an example 400 associated with cyclic shift mapping for multiplexed messages with different priorities in accordance with this disclosure. As shown in fig. 4, example 400 includes communication between base station 110 and UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network, such as wireless network 100. Base station 110 and UE 120 may communicate via a wireless access link (which may include uplink and downlink).

As shown in fig. 4A and further illustrated by reference numeral 410, UE 120 may use the selected cyclic shift to generate a multiplexed message. For example, UE 120 may select a set of cyclic shifts from a plurality of possible sets of cyclic shifts and may select a cyclic shift within the set of cyclic shifts and may generate a multiplexed message to use the selected cyclic shift. In this case, the selection of the set of cyclic shifts may be based at least in part on a value of a first high priority payload of the multiplexed message, and the selection of the cyclic shifts within the set of cyclic shifts may be based at least in part on a value of a second low priority payload of the multiplexed message. For example, when the multiplexed message conveys an SR as a high priority payload and a HARQ feedback message as a low priority payload, UE 120 may select a set of cyclic shifts to indicate the value of SR (e.g., positive or negative) and a cyclic shift to indicate an a/N value (e.g., {0} or {1} for 1-bit HARQ feedback, or {0,0}, {0,1}, {1,1} or {1,0} for 2-bit HARQ feedback) within the selected set of cyclic shifts.

In some aspects, UE 120 may select a set of cyclic shifts and/or cyclic shifts based at least in part on the configuration information. For example, UE 120 may receive a set of possible cyclic shifts identifying possible values for high priority payloads and possible cyclic shifts for low priority payloads from base station 110. Additionally or alternatively, UE 120 may receive other signaling identifying a set of possible cyclic shifts or cyclic shifts. Additionally or alternatively, UE 120 may use stored configurations defining a set or cyclic shift of possible cyclic shifts. In some aspects, UE 120 may be configured with multiple configurations for multiple different possible payloads. For example, UE 120 may include a first configuration for cyclic shift set and cyclic shift of a first set of possible payloads and a second configuration for cyclic shift set and cyclic shift of a second set of possible payloads. In this case, UE 120 and/or base station 110 may communicate to synchronize which payload set is to be included in the multiplexed message and, correspondingly, which configuration is to be used. Additionally or alternatively, UE 120 and/or base station 110 may operate in accordance with stored configurations defining which payload set is to be included in the multiplexed message (e.g., based at least in part on timing, order, mode of operation, etc.), and accordingly which configuration is to be used.

As a first example 411 and as shown in fig. 4B, UE120 may be configured to transmit a multiplexed message conveying a high priority SR and a low priority 1-bit HARQ feedback message. In this case, UE120 may select a first set of cyclic shifts (e.g., CS values 0 or 1) to convey negative SRs and a second set of cyclic shifts (e.g., CS values 6 or 7) to convey positive SRs. The interval between the first and second sets of cyclic shifts (in this example, 5 cyclic shifts) may be defined as a first value d1. In some aspects, the interval d1 may be maximized in the available space (e.g., would be 5 cyclic shifts in this example). In some aspects, the interval d1 may be configured to be greater than an interval d2 between cyclic shifts within the set of cyclic shifts (e.g., 1 cyclic shift in this example). In this way, by having d1> d2, UE120 increases the likelihood that base station 110 successfully decodes high priority SRs (e.g., by making it easier to distinguish whether the CS value used is 0 or 1 or 6 or 7). Similarly, UE120 may select a cyclic shift from within the set of cyclic shifts to convey the value of the 1-bit HARQ feedback message for low priority (from the cyclic shift with interval d 2). For example, when UE120 conveys a negative SR (cyclic shift set 0 or 1), UE120 may select CS value 0 for a/N value {0} and CS value 1 for a/N value {1}. Similarly, when UE120 conveys a positive SR (cyclic shift set 6 or 7), UE120 may select CS value 6 for a/N value {0} and CS value 7 for a/N value {1}. Although it may be more difficult to differentiate low priority payloads at base station 110 than if the low priority payloads had a larger spacing (e.g., as may occur if d2> d 1), UE120 ensures prioritization of high priority payloads (e.g., by having d1> d 2) while still conveying low priority payloads (rather than dropping low priority payloads). In this way, UE120 communicates low priority payloads without negatively impacting the likelihood of successfully decoding high priority payloads, thereby improving network performance.

As a second example 412 and as shown in fig. 4C, UE120 may be configured to transmit a multiplexed message conveying a low priority SR and a high priority 1-bit HARQ feedback message. In this case, UE120 may select a first set of cyclic shifts (e.g., CS values 0 or 1) to convey the a/N value {0} and a second set of cyclic shifts (e.g., CS values 6 or 7) to convey the a/N value {1}. In this way, by maximizing the interval between the cyclic shift sets, UE120 increases the likelihood that base station 110 successfully decodes the high priority HARQ feedback message. Similarly, UE120 may select a cyclic shift from within the set of cyclic shifts to convey the value of the low priority SR message. For example, when UE120 conveys an a/N value {0} (cyclic shift set 0 or 1), UE120 may select CS value 0 for negative SRs and CS value 1 for positive SRs. Similarly, when UE120 conveys the a/N value {1} (cyclic shift set 6 or 7), UE120 may select CS value 6 for negative SR and CS value 7 for positive SR.

Although some implementations are described herein in terms of a particular number of particular CS values, other configurations of the arrangement of the cyclic shift sets, the type of multiplexed messages, etc. are possible. For example, UE120 may select from cyclic shift sets 1 or 2 and 7 or 8 (instead of cyclic shift sets 0 or 1 and 6 or 7). Similarly, in another configuration, UE120 may select from CS values 0 through 23 (e.g., and select cyclic shift sets 0 or 1 and 12 or 13) instead of from CS values 0 through 11. Similarly, UE120 may select from other numbers of sets of cyclic shifts, rather than from two possible sets of cyclic shifts, as described in more detail herein.

As a third example 413 and as shown in fig. 4D, UE120 may be configured to transmit a multiplexed message conveying a high priority SR and a low priority 2-bit HARQ feedback message. In this case, UE120 may select a first set of cyclic shifts (e.g., CS values 0,1, 2, or 3) to convey negative SRs and a second set of cyclic shifts (e.g., CS values 6, 7, 8, or 9) to convey positive SRs. Similarly, UE120 may select a cyclic shift from within the set of cyclic shifts to convey a value for the low priority 2-bit HARQ feedback message. For example, when UE120 conveys a negative SR (cyclic shift set 0,1, 2, or 3), UE120 may select CS value 0 for a/N value {0,0}, CS value 1 for a/N value {0,1}, CS value 2 for a/N value {1,1}, and CS value 3 for a/N value {1,0 }. For example, when UE120 conveys a positive SR (cyclic shift set 6, 7, 8, or 9), UE120 may select CS value 6 for a/N value {0,0}, CS value 7 for a/N value {0,1}, CS value 8 for a/N value {1,1}, and CS value 9 for a/N value {1,0 }. Although it may be more difficult to differentiate low priority payloads at base station 110 than low priority payloads having a larger spacing, UE120 still conveys low priority payloads (rather than dropping low priority payloads) without negatively impacting the likelihood of successfully decoding high priority payloads with a maximized spacing within the available space (e.g., 12 cyclic shifts) for the number of bits to be conveyed using the 12 possible CS values, thereby improving network performance.

As a fourth example 414 and as shown in fig. 4E, UE120 may be configured to transmit a multiplexed message conveying a low priority SR and a high priority 2-bit HARQ feedback message. In this case, UE120 may select a first set of cyclic shifts (e.g., CS values 0 or 1) to communicate a/N values {0,0}, a second set of cyclic shifts (e.g., CS values 3 or 4) to communicate a/N values {0,1}, a third set of cyclic shifts (e.g., CS values 6 or 7) to communicate a/N values {1,1}, or a fourth set of cyclic shifts (e.g., CS values 9 or 10) to communicate a/N values {1,0}. Similarly, UE120 may select a cyclic shift from within the set of cyclic shifts to convey a value for the low priority SR message. For example, when UE120 conveys an a/N value {0,0} (cyclic shift set 0 or 1), UE120 may select CS value 0 for negative SR and CS value 1 for positive SR.

As a fifth example 415 and as shown in fig. 4F, UE120 may be configured to transmit a multiplexed message conveying a high priority SR and a 2-bit HARQ feedback message comprising a high priority first bit and a low priority second bit. In other words, the first high priority payload may be a 1-bit SR and a 1-bit HARQ feedback, and the second low priority payload may be a 1-bit HARQ feedback. In this case, UE120 may select a first set of cyclic shifts (e.g., CS values 0 or 1) to convey a negative scheduling request and an a/N value {0} (collectively "{ negative, 0 }), a second set of cyclic shifts (e.g., CS values 3 or 4) to convey { negative, 1}, a third set of cyclic shifts (e.g., CS values 6 or 7) to convey { positive, 1}, or a fourth set of cyclic shifts (e.g., CS values 9 or 10) to convey { positive, 0}. Similarly, UE120 may select a cyclic shift from within the set of cyclic shifts to convey the value of the low priority HARQ feedback bits. For example, when UE120 conveys { negative, 0} (cyclic shift set 0 or 1), UE120 may select CS value 0 for a/N value {0} (e.g., resulting in total a/N value {0,0 }) and CS value 1 for a/N value {1} (e.g., resulting in total a/N value {0,1 }). In another example, rather than a high priority SR bit, a high priority a/N value, and a low priority a/N value, UE120 may use a similar set of cyclic shifts to convey, for example, a first high priority bit (e.g., SR bit), a second high priority bit (e.g., a/N value), and a third low priority bit (e.g., a bit that is a third type of PUCCH bit—neither SR bit nor a/N value).

As a sixth example 416 and as shown in fig. 4G, UE 120 may be configured to transmit a multiplexed message conveying a low priority SR and a 2-bit HARQ feedback message comprising a high priority first bit and a low priority second bit. In other words, the first high priority payload may be 1-bit HARQ feedback and the second low priority payload may be 1-bit HARQ feedback and 1-bit SR. In this case, UE 120 may select a first set of cyclic shifts (e.g., CS values 0,1, 2, and 3) to convey the a/N value {0} or a second set of cyclic shifts (e.g., CS values 6, 7, 8, or 9) to convey the a/N value {1}. Similarly, UE 120 may select a cyclic shift from within the set of cyclic shifts to convey the values of the low priority HARQ feedback bits and the low priority SR bits. For example, when UE 120 conveys {0} (cyclic shift set 0,1, 2, or 3), UE 120 may select CS value 0 for { negative, 0} (e.g., resulting in a total a/N value {0,0 }), CS value 1 for { negative, 1} (e.g., resulting in a total a/N value {0,1 }), CS value 2 for { positive, 1} (e.g., resulting in a total a/N value {0,1 }), or CS value 3 for { positive, 0} (e.g., resulting in a total a/N value {0,0 }).

Returning to fig. 4A and indicated by reference numeral 420, UE 120 may transmit the multiplexed message using the selected cyclic shift. For example, using the selected cyclic shift of the selected set of cyclic shifts, UE 120 may transmit a multiplexed message including a high priority payload and a low priority payload. Additionally or alternatively, UE 120 may transmit a multiplexed message with another set of payload priorities or a different number of payloads, etc.

As shown in fig. 4A and further illustrated by reference numeral 430, the base station 110 can decode the multiplexed message using the selected cyclic shift. For example, base station 110 may determine a set of cyclic shifts that UE 120 uses to transmit multiplexed messages to determine a value of a high priority payload. As an example, UE 120 may determine whether the multiplexed message is transmitted using cyclic shift 0 or 1 or CS value 6 or 7 to determine, for example, whether the high priority bits are negative SRs or positive SRs. Additionally or alternatively, the base station 110 may determine a cyclic shift within the set of cyclic shifts to determine a value of the low priority payload. For example, within CS values 0 and 1, the base station 110 may determine whether the cyclic shift is 0 for the A/N value {0} or 11 for the A/N value {1} as described above. Other arrangements or configurations of cyclic shift sets, cyclic shifts, and/or payloads are possible, as described above.

As indicated above, fig. 4A-4G are provided as examples. Other examples may differ from the examples described with respect to fig. 4A-4G.
